Welcome to our blog!
We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

   When insurance companies request a 4-point inspection for older homes, as they are doing more often lately, if the water heater is over about 25 to 30 years old they will request that it be replaced as a requirement for coverage.

   There are several things you can do to extend the life of an older water heater, such as draining the sediment from the bottom of the tank every couple of years and replacing the sacrificial anode as necessary, but the best way to avoid a water heater failure and subsequent water damage is to just replace it.


While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
